COMBINATION CLAW AND PINCI-I BAR.

To all whom it may concern:

Be it known that I, MARoUs S. CLARKE, a citizen of the United States, and resident of Houston, Texas, have invented certain new and useful Improvements in Combination Claw and Pinch Bars, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a combination claw and pinch bar particularly adapted for use in railway track construction, the object of my invention being to equip an ordinary pinch bar with a pivoted shackle or claw, and the tool thus formed being adapted for performing a number of operations incident to the laying, shifting and removal of railway track rails.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:

Figure l is a front elevation of a combination tool of my improved construction; Fig. 2 is a side elevation, partly in section, of the tool, which View is taken on the line 2-2 of Fig. 1; Fig. 3 is an elevation of the lower portion of the tool and showing it applied for use as a claw bar; Fig. 4 is an elevation of the lower portion of the tool, and showing it applied for use as a lifting or skidding bar; Fig. 5 is an elevation of the lower portion of the tool and showing it applied for use in setting spikes, with the pivoted shackle lifted; Fig. 6 is an elevation of the lower portion of the tool showing same applied for use in pulling an ordinary straight bolt or the like; Fig. 7 is an elevation of the lower portion of the tool, showing the same applied for use as a pinch bar; Fig. 8 is an elevation of the lower portion of the tool, showing the same applied for use in pulling spikes between a rail and guard rail; and Fig. 9 is an elevation of the lower portion of the tool showing the same applied for use in pulling spikes on the ends of bridge ties. (In this figure the shackle is reversed.)

Referring by numerals to the accompanying drawings: 1 designates the body of the tool, and which forms the handle thereof, the same being in the form of a straight bar,

the upper end of which is curved laterally to a slight degree and pointed, as designated by 2. The lower end of the bar is bent laterally, as designated by 3, and said laterally bent end terminates in a sharpened point, as designated by 4. The body 1 formed as described may be regarded as a pinch bar.

A bolt 5 passes transversely through the bar, immediately above the bent portion 8, and pivotally mounted on said bolt and bearing against the side faces of the bar are the upper ends of the side plates of a U-shaped shackle or claw 6, the lower end of which is provided with a pair of forwardly projecting points 7, the space between which is of suificient width to accommodate the upper portion of an ordinary railway spike. The shackle or claw 6 is normally positioned immediately in front of the bent portion 3 of the pinch bar, and the rear edge of the lower end of said shackle or claw is provided with a horizontally disposed sharp edge 8, which normally engages against the corresponding edge or point 4 on the lower end of the pinch bar. The under surface of the claw or shackle 6 is curved slightly, as designated by 9, and when said claw or shackle occu pies a normal position this curved surface forms a continuation of the curved surface 10 formed on the lower end of the bent portion 3. The shackle or claw 6 may be removed and reversed by removing the cotter pin which passes through one end of the bolt 5, and in removing the bolt 5.

Then the tool is used as an ordinary claw bar, the claw or shackle 6 is positioned immediately in front of the bent portion 3 and the points 7 are engaged beneath the head of a spike, as shown in Fig. 8, and the upper portion of the pinch bar is now swung downward, and by reason of the elongated bearing formed by the curved surfaces 9 and 10, the spike may be pulled vertically without bending. Then the device is used as a lifting or skidding bar, the lower end of the bent portion 3 is applied to the side of the rail, as shown in Fig. 4, with the claw or shackle bearing against the tie and forming a strut on which the bar fulcrums during the lifting or skidding movement. Where the tool is used for setting spikes, the claw or shackle is swung upward into the position seen in Fig. 5, and the point et at the lower end of the tool is engaged beneath the head of the spike and said tool fulcrums upon the ball of the rail during its operation.

In Fig. 6 the device is shown as being used for pulling straight bolts or boat nails, and when put to this use the point 4 is engaged against one side of the bolt and the shackle extends over the bolt with the edge 8 bearing against the side of the bolt opposite the side against which the point 4 bears.

In Fig. 7 the tool is shown in use as a pinch bar for imparting movement to a car wheel, and where the tool is so used the end of the bar is positioned between the top of the rail and the periphery of the wheel and the shackle or claw rests on top of the ball of the rail to form a base or fulcrum for the bar.

In Fig. 8 the tool is shown as being used for pulling spikes between track and guard rails, and where so used the point 4.- engages against one side of the head of the spike and the edge 8 of the shackle engages against the opposite side of the head.

In Fig. 9 the tool is shown as applied for use in pulling spikes on the ends of bridge ties, and where so used the claw or shackle is reversed and the points 7 are engaged beneath the head of the spike and the lower end of the portion 3 bears on the tie, thus permitting the manipulator of the tool to stand in the center of the track while pulling the outside spikes.

Other uses for a tool of my improved construction will readily suggest themselves to persons engaged in railway track construction, and thus I provide a simple, inexpensive tool which can be advantageously employed in performing a number of different operations in the laying and removal of railway track rails, and the like.

I claim:

1. The combination with a pinch bar of a U-shaped shackle pivotally mounted on one end of the bar and there being a sharp edge formed on the lower end of said shackle.

2. The combination with a pinch bar of a U-shaped shackle pivotally mounted on one end of the bar, and a pair of prongs formed integral with the lower end of said shackle.

3. The combination with a pinch bar of a U-shaped shackle pivotally mounted on one end of the bar, there being a sharp edge formed on the lower end of said shackle, and a pair of prongs formed integral with the lower end of said shackle.

4. The combination with a pinch bar, of a removable and reversible shackle, which shackle is provided on its lower end with a spike claw by means of which spikes may be pulled with said shackle.

5. The combination with a pinch bar, one end of which is bent laterally and pointed, of a removable and reversible shackle, which shackle is provided on its lower end with a spike claw by means of which spikes may be pulled with said shackle.

In testimony whereof, I have signed my name to this specification in presence of two subscribing witnesses.

MARCUS S. CLARKE.
